So your best efforts to try to have a uniform system don't always work. That's fair.
It may be an unfair question on the federal level, but again, the bulk of my riding is rural, with very small villages, lots of acreages and farms. A lot of them have communal water systems where they may have one or two wells, and pipes go out from there. I assume that would be difficult data to try to track down in terms of what they were using.
